2 Claims. (01. 164-118) The present invention relates to shoe machines hang ng head M. A die carrier in the form of a and more particularly to die holders for use in a rectangu Sliding block 8 is mounted in machine for performing a combined ink-marking 7 lower part of the head It in axial alignment with and perfgrating operafln the plunger, (not shown), as described more fully For purposes of disclosure the various features in my application Serial No. 128,314 of which this of the present invention are illustrated and deis a division. The connection between the plunger scribed as embodied in the Model 3, machine and the die carrier is generally the same in conmanufactured by Western Supplies Company, structionand mode of operation asthe connecunder my prior patents, Nos. 1,834,919 and tion shown in my prior Patent No. 1,938,678, so 9 1,938,678, which machine has a wide use in the that it is nne ess ry to repeat that description. 10 manufacture of shoes to perform many different The bottom face of the die carrier 28 is flat, operations (Fig. 3), to receive flatwise one face of a plate 36 Heretofore Western Supplies Company per- DIOVIded W a P O mutilated pins 31 which formed the combined ink-marking and perforatenter vertical sockets 38 formed in the die car- I ing operation upon the well-known Western cutrier 28. The plate 36 is secured to the die carrier out machine. 28 by frusto-conical surfaces 39, (Fig. 2), which The principal objects of the present invention engage the mutilated portions of the pins 31, are to produce a simple, inexpensive and efficient respectively. The surfaces 39 are formed on die holder for a combined ink-marking and perelongated pins 40 mounted t lid in horizontal to forating machine, particularly in the form of an p ngs 4| formed in the die carri r 23, Each ,9 attachment to the Model B. machine, and to simsurface 39 is held in engagement with the mutiplify and improve the die holder, particularly, lated portion of one of the pins 31 by a spring 42 with respect to the securing of the chips cut out coiled about a reduced portion of the pin 40 and of the work by the die and the discharge of the interposed between the pin 40 and a web 43 of 5 die holder for ready insertion in and removal the die carrier 28, a screw ll carried by the end a from the machine of the retained chips. of the pin 40 acting by engagement with the web To the accomp i h of these obleets, and 43 as a stop for limiting the movement of the pin such others as may pp hereinafter. the varunder the influence of the spring. Both pins 40 ious features of the present invention reside in are connected to a common handle 45 for operat- 80 certain devices. combinations and arrangement ing them to release the pins 31, there being a stop of parts hereinafter described and then set forth 5 on t die carrier 2 f r limiting the inward r ad y d in detail n the a p claims movement of the handle. The pins 40, adjacent wh c Possess tages readily appa li0 the surfaces 39, are provided with a cylindrical those skilled in the art. portion 41 of reduced diameter to permit the pins 35 The various features of the present invention 31 to be readily withdrawn from the sockets 36 will be readily understood from an inspection of when the handle 5 is pushed inwardly I r the accompanying drawing illustrating the best The plate 35 is riveted to the reduced upper form of the invention at present known to the ends of four posts a the lower reduced ends of inventor, in which 0 Figure l is a detail view in perspective of sufli- :2: i gggfifi 1 E2 2: 1. g:: gg 40 cient portions of the combined ink-marking and posts 48 bein g riveted to the plate 5|.

Integrally formed of the block 49 and the p of which is secured with the base is an irregularly shaped boss l2 conto the w ow ed es of t e p a e e wall stituting the work supporting bed. An overhangforms a a ber 63 for retaining e chips ing arm is integrally cast with the base 9 and or pills formed by the cut-out die 52 and. the per- 5 includes the standard l3, (Fig. 1) and the overforating tubes which work up from the dies into I the chamber 63 through inlet passages 64 and 65, respectively.

The plate 36 is provided with an outlet 66 which is normally closed by the bottom of the die carrier 28. To clear the chamber 63 of chips the handle 45 is pressed inwardly to release the pins 31, thus permitting the plate 36 and the die structure assembled therewith to be withdrawn from the die carrier 28. After the plate 36 has been separated from the bottom of the die carrier 28, the die structure may be turned into an upside down position whereupon the chips or pills in the chamber 63 may beshaken out through the outlet 66.

What is claimed as new, is:

1. A perforating machine having, in combination, a die carrier having sockets, a die carrier engaging plate having mutilated pins received in the sockets, respectively, and means for locking the plate and carrier together comprising frustoconical surfaces, one for each pin carried by the die carrier, springs for pressing the surfaces into engagement with the mutilated portion of the pins, and a common operating handle for moving the surfaces to disengage the pins.
